Title: Prilling
IPC: B01J2/04
Filed: 1973-02-09
Abstract: 1459781 Prilling FISONS Ltd 7 Jan 1974 [9 Feb 1973 18 April 1973] 6592/73 and 18609/73 Heading B5A [Also in Divisions C1 and C2] Molten material such as sulphur, urea, NPK fertilizer or an alkali-metal hydroxide is prilled by causing droplets of the material to travel against a counter-current of drops of material which volatalises on contact with the molten material suspended in a gas stream saturated with respect to the volatile material so that at least the surface of the drops solidifies before collection. Droplets, formed by flowing through a perforated plate, by spraying or by a spinning basket fall down a tower into which is upwardly sprayed water or a low boiling point alcohol, ketone or halogenated hydrocarbon. Air, N 2  or CO 2  is fed into the spray or down into the tower by the upcurrent. Tangential sprays may cause swirling of the upcurrent. Material for incorporation in the molten droplets may be dissolved in the volatile material. After falling through a portion of the tower free from drops of volatile material, so that excess volatile material may evaporate, the droplets are collected in a liquid or fluidized bed of material which forms a coating on the droplets, or in the liquid forming the volatile drops, or in a solvent which removes excess of the volatile material.

Patent GB-1415824-A (GB)
Title: Addressing system
IPC: H04Q9/14
Filed: 1974-02-14
Abstract: 1415824 Selective signalling INTERNATIONAL STANDARD ELECTRIC CORP 14 Feb 1974 6756/74 Heading G4H  An addressing system in a master station provides the addresses of a plurality of outstations and, from a counter, the addresses of groups of devices thereat, stored values being used to delimit the counting. As disclosed, a given group of devices at a given outstation is addressed by loading a shift register with a start bit, the outstation address from a counter, the group address from the first-mentioned counter, and mode and check bits. A typical outstation contains a first set of groups of devices requiring continuous monitoring, and a second set of groups of devices which change condition only infrequently. The addressing system, in a first mode, addresses each group of the first set in turn, in each outstation in turn, and for each group a message is sent to a shift register in the master station from the outstation, consisting of a start bit, an indicator bit, device condition bits and check bits. If the indicator bit indicates that any device in the second set of groups in the substation has changed state, the system completes addressing of the first set in this outstation, then addresses the groups of the second set in this outstation in turn, in a second mode, before returning to the first mode to address the next outstation. The outstation counter, via a decoder, selects a row of a diode-matrix memory, the row specifying the number of groups in the first set, and the address of the first group of the second set, at the respective outstation. In the first mode, for a given outstation, the number of groups in the first set is loaded into a comparator and compared with the group counter which is incremented by the start bit in each message from outstations, equality resetting the group counter and incrementing the outstation counter (assuming the second mode is not entered). In the second mode, the address of the first group of the second set is loaded into the group counter which is incremented by the start bit in each message from the outstation, until capacity is reached when the group counter is reset and the outstation counter is incremented to return to the first mode. In a modification, the comparator is used in the second mode as in the first, but the group counter counting down from capacity (until equality with the memory is reached) in the second mode.

Title: Tape transport assembly for magnetic tape recorder and reproducer sets
IPC: G11B15/43
Filed: 1974-02-14
Abstract: 1456781 Automatic control of speed O H RICHT 14 Feb 1974 [16 Feb 1973] 6797/74 Heading G3R [Also in Division G5] A reversible magnetic tape transport comprises two capstans 2, 3 associated with respective drive motors 9, 8, the drive shafts of which are coupled together via discs 12 and 11 and a belt 10, the transport being arranged so that the one of motors 8, 9 which is downstream of the other relative to the chosen tape movement direction is energized to drive the tape via both capstans simultaneously. A reversing switch 13 connects the non-energized, or upstream, motor to an adjustable electrical braking resistor 14 to control tape tension. The capstans 2, 3 are the output drive shafts of the motors which are commutator motors having iron-free rotors, a switch 19' short-circuiting the rotor windings when the transport is stopped. The non-energized motor acts as a tacho-generator giving a control signal input to the inverting input line 15 of differential input transistor servo circuit 16, the input on line 15 being compared with a reference signal supplied to non-inverting input line 17 via a speed selector switch 18, the output of circuit 16 powering the energized motor at a constant speed. To allow adjustment to eliminate working tolerances of the motors 8, 9, the resistor 14 may be replaced by a circuit comprising two fixed resistors (14a), (14b), and two adjustable resistors (14c), (14d), Fig. 2 (not shown). The pressure of pinch rollers 4, 5 against the tape 1 is maintained during starting and stopping and tape reversal. The tape transport is applicable to cassette-tape recorders.

Title: Method of and machine for tying parcels by means of wire
IPC: B65B13/28
Filed: 1932-03-07
Abstract: 387,153. Wiring bales &c. WOLF, P., 2, Bruerstrasse, Kalk, Cologne, Germany. March 7, 1932, No. 6853. Convention date, Dec. 28, 1931. [Class 45.] In a bale &c. wiring apparatus wherein one end of the wire is clamped at a fixed point and the other end is secured to tensioning mechanism, after the tensioning has been effected the wire is clamped and cut between the twisting pinion and the tensioning means, the operation of the means effecting the clamping and cutting simultaneously unlocking the means for operating the twisting pinion. The tensioning means may comprise the notched drum 17, Fig. 1, operated by the ratchet lever 19 or may comprise a pair of serrated rollers 22, 24, Fig. 3, between which the wire passes, and which are rotated in opposite directions from the ratchet lever 19 through a train of toothed gearing. The serrated roller 22 is carried by an eccentric 23 so as to be movable away from the other roller by means of a lever 27. A spring 28 normally draws the rollers into contact to a degree limited by an adjustable stop 30. A lug 27a on the lever 27 lies over the contacting portions of the serrated rollers to prevent the wire slipping sidewise. The free end of the wire is clamped between a serrated eccentrically mounted disc 3, Fig. 1, and a serrated anvil 1a. The intermediate clamping and cutting means comprise sliding members 10, 11 which are depressed in succession by rotation of a lever 13. The lever 13 is eccentrically mounted in a link 14 is which provided with cam surfaces coacting with the upper ends of the members 10, 11 and is pivoted eccentrically to a rotatable bolt 15. An arm 16, Fig. 5, is pivoted on the rear end 12a of the shaft of the lever 13 to which a driving pin 16a also is secured. A member 35 having an annular groove 35a in which the arm 16 normally engages is slidably but not rotatably mounted on the shaft 8 which operates the gear wheel 7 meshing with the slotted twister pinion 6, a pin 36 having enlarged heads and projecting from the shaft 8 engaging in axial grooves in the member 35. This member is normally pressed by a spring 37 to a position in which a lug 31a projecting from an arm 31 loose on the shaft 8 engages in a notch 35d in the member 35 to lock the latter against rotation. On rotation of the lever 13 the arm 16 first moves the member 35 against the spring 37 so that the notch 35d rides clear of the lug 31a and the arm is raised by a spring 32. On completion of the movement of the lever 13 the arm 16 moves out of the groove 35a and the member 35 is moved back by the spring but is not locked by the lug 31a since the latter no longer registers with the notch 35d so that rotation of the shaft 8 and twister pinion may now be effected. As the end of the twisting operation is reached the notch 35d re-registers with the lug 31a and moves the arm 31 downwards to a limited extent and the sleeve 35 and shaft 8 become re-locked. A slight reverse rotation of the shaft 8 is effected by the spring 32 and is limited by a pawl 39 engaging a recess in the hub of the gear wheel 7.

The thermal element controls hot and cold water valves 5 and 6 secured (the valve 5 adjustably) to a tube 8 which is loaded by a spring 19 to maintain the thermal element in contact with the spindle 12.
Patent GB-564659-A (GB)
Title: Process for the production of organic sulphur compounds
Filed: 1943-05-04
Abstract: p-Acetylaminobenzenesulphenamide is prepared by reacting 4 : 41 - diacetyldiaminodiphenyldisulphide with chlorine and treating the product with an amine compound, characterised in p  that the treatment with chlorine is carried out in carbon tetrachloride solution using less than three mols. of chlorine for each mol. of the disulphide.  The addition of chlorine is preferably carried out by adding a solution of chlorine in carbon tetrachloride to a carbon tetrachloride suspension of the disulphide.  The amine compound may be added to the chlorinated product in the carbon tetrachloride in the same vessel as served for the chlorination, or the chlorinated product may be removed by filtration, dissolved in another organic solvent such as acetone and then treated with the amine compound. The amount of amine compound should be regulated according to the amount of chlorine used in order to absorb the acidic products of reaction.  The amine compound may be ammonia or an aliphatic, alicyclic, aromatic or heterocyclic amine.  Compounds mentioned include methylamine, ethylamine, butylamine, amylamine (normal, secondary or iso), octylamine, aniline toluidine (ortho, meta or para), naphthylamine (a  or b ), guanidine, phenylguanidine, aminopyridines such as 2-aminopyridine, aminoquinolines, aminoisoquinolines, aminopyrimidines such as 2-aminopyrimidine or 2-amino-4 : 6-dimethylpyrimidine, and aminothiazoles such as 2-aminothiazole, 2 - amino - 4 - methyl - thiazole, and 2-aminobenzthiazoles.  In addition, organic cyclic imines such as piperidine and morpholine may also be used.  In examples: (1) 4 : 41-diacetyldiaminodiphenyldisulphide is dispersed by grinding in carbon tetrachloride, and a carbon tetrachloride solution of chlorine is added slowly at 0 DEG  C. to form a yellow insoluble paste to which is added a benzene solution of 2-aminopyridine.  The reaction is very slowly warmed and the carbon tetrachloride removed.  Excess aminopyridine is removed by treatment with caustic soda.  (2) The yellow insoluble paste of the chlorinated product formed as in example (1) is filtered and washed with petrol ether and then added to an acetone solution of 2-aminopyridine.  The acetone is removed and the excess aminopyridine removed with caustic soda as before. Specifications 551,205, 551,206, 551,207, 551,681 and 553,269 are referred to.
